#

how can i make my unity window go orange like this when something happens out of focus?

image.png
steep rose
#

I believe it does do that already

#

you just cant be tabbed into it, and you have to start the application

#

also may i ask why? thats kinda strange that you would want that

#

also this is not a code related question, or unity at all

ivory bobcat
#

Cache the local euler angle property, modify it then reassign it to the local euler angle property. For example: cs var lea = transform.localEulerAngles; lea.x = ... transform.localEulerAngles = lea;
Assuming you're simply having difficulties with c# properties relative to Unity's strange naming convention for properties - they're camelCase and not Pascal for some reason..

stuck palm
#

im talking about like my built project

steep rose
#

thats a windows thing

stuck palm
#

not the editor

steep rose
#

not a unity thing

#

windows already does that normally iirc

stuck palm
#

im talking about based on a unity event

#

like if youre tabbed out and you load into a game

#

you send an event or whatever

steep rose
#

but as stated its not a unity thing

#

afaik

#

you can write your own code via c++ or python or something do mess with windows if you really want that

#

its most likely possible, i just dont know how

lethal elbow
steep rose
#

you can also clamp various ways using custom logic and such

#

i dont do that though

lethal elbow
#

I probably should have gone straight to the documentation without asking

lethal elbow
steep rose
#

then use the documentation

iron wing
#

where is a good place to ask about my ide?? everytime I open a script (at least i think thats whats happening) it looks like I can't use autocomplete. only way for it to show up again is reopening visual studio code. this is really getting on my nerves now :(

oddly enough i've already followed all the steps for that. it works fine but every now and then it stops and I've gotta relaunch vs for the unity extension to work properly.

that's why, remove VS Code

The last line of this is stopping the rotation of my object

  Vector3 pitch = transform.localEulerAngles; 
                
                currentMousePosition = Input.mousePosition.y;
                mouseMovement = currentMousePosition - startMousePosition;

                transform.Rotate(Vector3.right, -mouseMovement * speed * Time.deltaTime);

                pitch.x = Mathf.Clamp(pitch.x, -30f, 30f);


                startMousePosition = currentMousePosition;

                transform.localEulerAngles = pitch;
#

Nevermind im a dummy, I rearranged everything to the top 🙂

languid spire
#

why would you do a Rotate and set the eulerAngles at the same time?

ivory bobcat
lethal elbow
#

There is an issue where the object gets to 0 on rotation.x and then it jumps to the max clamp value

ivory bobcat
#

Euler angles acquired from the property (a Quaternion) would vary.

languid spire
ivory bobcat
lethal elbow
steep rose
#

read from the localrotation of the transform

lethal elbow
# 
                Quaternion pitch = transform.localRotation;
                pitch.x = Mathf.Clamp(pitch.x, -30f, 30f);
                transform.localRotation = pitch;

Like this?

short hazel
#

Quaternions don't store angles in degrees, so that won't work

lethal elbow
#

It did not work as said haha

short hazel
#

One Quaternion can be represented by multiple different Euler Angles. So you shouldn't be reading from .eulerAngles at all, since the values you get can vary wildly

#

Store the rotation in a vector variable (or two float variables), and accumulate the mouse rotation into that. Then clamp and apply to .eulerAngles once

queen adder
#

Is it possible to refrence a Monobehavior script on a Non monobehavior script

short hazel
#

Yes, MonoBehaviour is a type like others

#

Just make a variable of that type (or the precise script type you need)

rich adder
#

just keep in mind you have no inspector so you have to pass the reference somehow so its not null

queen adder
rich adder
#

simple DI with a method

queen adder
#

DI?

short hazel
#

Or a constructor

wintry quarry
#

You almost certainly want to use your actual script class and not MonoBehaviour

tiny bloom
#

im detecting right clicks on objects in canvas
i instantiate a UI prefab
the parent has an image with 0 alpha, to detect clicks and there's children as shown

however when i right click the child image, it detects the child image first before detecting the image component on the parent gameObject
i understand this is the normal behavior of unity
but I want a clean way to change that.

this method returns all the item that the raycast passed through after i pass it the pointer click data

 List<RaycastResult> GetClickedItems(PointerEventData eventData)
 {
     List<RaycastResult> results = new List<RaycastResult>();
     graphicRaycaster.Raycast(eventData, results);

     return results;
 }

rich adder
#

you also have the static functions like FindObjectOfType if you don't need specific one, or its the only one. Or use the array version loop through them to find specific thing. Using injection is always better (pass it through a method like constructor too)

wintry quarry
#

If not just disable Raycast target on it

queen adder

class Sample
{
    public YourScript Script { get; }
    
    // Constructor
    public Sample(YourScript script)
    {
        Script = script;
    }
}

// Usage:
Sample s = new Sample(someScript);
#

Simple constructor injection

rich adder
#

cause one way or another you still need to grab that specific mb component, we don't know your setup so its hard to say how exact

lethal elbow
short hazel
#

Yes any of them

#

The read is the problem

#

x = t.eulerAngles;

queen adder
rich adder
#

this script ?

queen adder
#

Yes the script clickDetection

#

I dont have that yet I just wrote the code

rich adder
#

still confused on why you're passing it for tbh

lethal elbow
short hazel
#

None of them. Do NOT read euler angles

#

Only write to them

queen adder
rich adder
queen adder
#

!code

eternal falconBOT
lethal elbow
short hazel
#

Not that either

#

Store your rotation in variables

#

private float pitch; for example

#

Add input to that, clamp, build a vector or quaternion from that and write it to euler angles

lethal elbow
#

Oh did you mean the actual rotation process? I thought you meant the object's current rotation

short hazel
#

None of your code processes a "location" (=position), everyhting is a rotation

lethal elbow
#

Yeah sorry, I was rushing. I changed it up

short hazel
#

I don't understand your question

lethal elbow
#

I'm not sure if you want the angle of the object or the rotating itself (transform.rotate etc)

short hazel
#

Full angles are stored, not deltas (changes in rotation). Deltas are added to the full angles variables

#

pitch would contain the accumulation of all changes in rotation you've made by moving the mouse around

upper forge
#

So im using a box colider2D to trigger a dialogue box, but when i go over it the first time it works but the i have to enter the collider 2 times before it triggers again....

any ideas why this would be happening?

short hazel
lethal elbow
# 
 transform.Rotate(Vector3.right, -mouseMovement * speed * Time.deltaTime);

this is what I use to rotate the object, I should store this in Pitch?

short hazel
#

This rotates by an amount, so it is not correct if you need to use a variable containing a full angle

lethal elbow
#

I think getting the initial angle is where I am having the issue then

short hazel
#

You don't get the initial angle from anywhere. You set it to 0 in the code directly

#

private float pitch = 0; (individual variables) - or - private Vector3 rotation = Vector3.zero; (all-in-one)

rich adder
lethal elbow
short hazel
#

No, for the 3rd (? - I stopped counting) time, I said that we do not read the rotation from anywhere

wintry quarry
lethal elbow
#

I understand it now, This value (not linked to anything) will increase/decrease in proportion to the increment/decrement done by the transform.rotate

short hazel
#

By your mouse input*

#

Add mouse input to local rotation variable, clamp that

#

Write to object's location last. transform.localRotation = Quaternion.Euler(localRotationVariable)

#

Once! Do not use transform.Rotate() before or after since it'll overwrite/get overwritten by the one you just did

upper forge
#

Nothing is on the Sign Parent, does this help @rich adder

#

Also thank you for being patient with me, I should have gone bed a while ago so my brain isn't braining

upper forge
lethal elbow
# 
    currentMousePosition = Input.mousePosition.y;
                mouseMovement = currentMousePosition - startMousePosition;
                

                transform.Rotate(Vector3.right, -mouseMovement * speed * Time.deltaTime);
                
                startMousePosition = currentMousePosition;


              
                pitch = Mathf.Clamp(mouseMovement, -3000f, 3000f);
                transform.localRotation = quaternion.Euler(pitch);

This is what I have so far but i'm clearly not thinking when tired so I'm going to sleep. I will come back to it tomorrow. Thanks to the people who was patient and tried helping me out

My project works fine in the editor but no script load when doing a quick local build.

A scripted object (probably xyz) has a different serialization layout when loading.
After doing some research, this could be linked to using conditional compilation in script but this project is brand new and I don't use such directive in my code. Second problem could be my asmdef but I've enabled Any Platforms and restarted my editor.
I don't know what to debug next. Could someone help?

when i make a new C# Script some of the code in my Player Scrpit stops working like [SerializeField] and stuff and for some reason i cannot use

yes and its from this code is what the error says

You probably need to add a Rigidbody2D to the game object "Platform (2)". Or your script needs to check if the component is attached before using it.

Having an issue with structure placement. One of the structures works perfectly fine, while the other constantly flies towards the camera, even though the code only adjusts the Y values.

Been troubleshooting this and can't seem to narrow down the issue, the code is attached. It froze at the end because I placed it.

Also lag is due in part to game running in background.

Found the issue, the raycast was hitting the cube. Not sure why the same wasn't happening with the cannon though, but after deciding to try a new layer anyways, it worked.

hello, does anyone know why this happens? i thought i checked for missing teamControllers

the first screenshot was bad actually hold on

#

i have it continue if the object is null though

#

does it not work like that

wintry quarry
#

You're doing ship.transform

#

You can't do that if it's destroyed

#

You would need ship == null as the first condition

#

You're doing it after the dangerous stuff

The order of the or statements in the if code matters as they are processed left to right

Is there a limit to the amount of corners that can be generated from NavMesh.CalculatePath?

#

Hmmm. Probably not. Going to elaborate further in a second

#

So here's my problem:

Blue filled in square at top left is destination. There is a blue wireframe cube at the bottom right that is the beginning.

The gray spheres are nav mesh corners. The blue wireframe cubes are the nav mesh corners being translated into grid nodes.

Strangely, my issue isn't with the wireframe cubes, but the spheres. As you can see, they kind of, give up before the end destination. These are nav mesh corners. And I have no idea why they're just... giving up before the end destination.

How do i exclude this library file

You should put /Library/ in your .gitignore

Using version control in Unity

Get the latest .gitignore file from here. It should be placed at the root of your Unity project directory.

#

Your gitignore doesn't have the standard Unity stuff in it (like /[Ll]ibrary/), and committing those files is not only unnecessary, but also unreasonable

keen trout
#

the problems is i have made some changes in project that are also not getting commited

#

should I add /[Ll]ibrary/) this in gitignore

You should be adding everything from the gitignore linked above to your .gitignore

what if i use build and run

You cant build when there is an error

no they aren't

well, maybe, but you wouldn't be able to see it in that screenshot

the screenshot shows a nested interface

the ide doesn't look set up, you have no diagnostics

the class already inherits from MonoBehaviour, you can't inherit from multiple classes

where is PlayerLocomotionInput.IPlayerLocomotionMapActions coming from? it doesn't exist in the code you linked

its an interface he tries to inherit from, but as he tries to get it from the class itself AND its not there, it wont work. thats why I suggested him to look for his source of code again. rhetorical question more or less

Judging by the screenshot it looks configured, so I'm confused why you'd have an issue here

scenic maple
#

definitely not configured

burnt vapor
#

I don't know which one I am supposed to look at

scenic maple
#

that one's from the video

burnt vapor
#

The first one is not configured, the second one is

#

Then it's not configured

#

I'm surprised nobody mentions their ide must be configured then

Its installed BTW

#

This might have something to do with it:
Cannot find .NET SDK installation from PATH environment. C# DevKit extension would not work without a proper installation of the .NET SDK accessible through PATH environment. Rebooting might be necessary in some cases. Check the PATH environment logged in the C# DevKit logging window. In some cases, it could be affected how VS code was started.

burnt vapor
#

Sorry, no idea.

#

VSCode is generally not the best solution when it comes to Unity development

scenic maple
#

works well for me

#

but i also use vscode for all my development

#

so i know how to deal with a lot of its quirks :p

frozen plaza
#

is it possible to split a class into several files and have partial classes in them?

I tried but It's not possible to assign as a component anymore

languid spire
rich adder
frozen plaza
# languid spire absolutely

How?

I had the class in one file and could assign it fine..
then I split it into 3 files and made them all partial class but I can't assign it anymore

frozen plaza
rich adder
#

ehh easier to manage smaller components than monolith even if its split into multiples

#

maybe you have initial friction but the benefit pays off ten fold

frozen plaza
# languid spire absolutely

I tried it with an empty monobehavior class and it actually works.. not sure why it doesn't with my actual class

Hi folk, I have a technical question. why is SetActive so expensive? GameObject.SetActive() 2x in a single frame just consumes 0.3% CPU

#

is there a way to minimize it's usage?

#

I just want to stop it's ticks etc, so I can actually stop it's ticks manually and teleport it far away

#

I guess it's going to be more effective?

vernal spear
#

I'm using an object pool to minimize the effort of spawning an object, but enabling/disabling is not cheap as well as I see?

past leaf
#

Line 83 should be RemoveListener right?I'm not sure...
*A official sample(fps microgame)

image.png
past leaf
burnt vapor
#

Because if you don't, then the reference will persist and call the listener each time it is invoked

past leaf
#

Ok great,so that official got a mistake i think...

vernal spear
rich adder
#

what you're doing when those are active is more important to look at

cosmic dagger
# vernal spear is there a way to minimize it's usage?

Activating a GameObject calls OnEnable for each MonoBehaviour and continues to run their Update method(s). You can enable/disable specific scripts to start/stop their code from running, but you need to compare that performance to deactivating the GameObject . . .

night raptor
vernal spear
#

I guess its the CPU Usage, no?

languid spire
#

and that would be the cpu usage allocated to this process, not of your complete cumputer

inland kettle
#

I can’t get the screenshot cause of how fast the code runs, but mostly the collisions are detected up to a certain point, when the console doesn’t print the right tag anymore as shown in the video

#

Sorry for the late response

slender nymph
#

lmao "late", that was 5 days ago my guy. you can still screenshot it to show what happens even if the console is printing things quickly

inland kettle
#

5 days is a stretch

slender nymph

2 days whatever

@vernal spear regardless what you showed sounds quite much. It would require seeing the code and more of the profiler view to make sure you are not misinterpreting something or doing something in the code that makes it slow other than the SetActive call

inland kettle
#

after hitting the top wall it stops registering collisions in the console, ie works until 5th picture

you have an instance of that component in the scene with that variable unassigned

vernal spear

wintry quarry
wintry quarry
#

It's working fine I think

slender nymph
# inland kettle

so as i guessed 2 days ago when this issue initially started, your console is set to collapse so you aren't seeing the subsequent correct collisions

inland kettle
#

ohh yea thanks

inland kettle
slender nymph
#

so now you need to look at your code and debug the values you use to see why it behaves the way it is

inland kettle
#

reflection doesn't work though

inland kettle
#

using my initial code or with reflect?

slender nymph
#

the current code that uses Vector2.Reflect

#

use the log message I gave you as an example of how you can print multiple pieces of data in one log and print all of the relevant values to ensure they are what you expect them to be

inland kettle
#

okay thanks

#

uhh what values should I be caring about

slender nymph
#

look at your code to find out

stuck palm
#

wow horrible screenshot

#

but you get the idea

inland kettle
slender nymph
#

print the values where you are going to use them. there's no sense in printing them in other methods, you need to know what they are at the time you use them so you understand what is happening

inland kettle
#

this is what I did

#

I printed the values and it printed wrong values

#

not what I expected

slender nymph
#

that's not helpful because you don't see the inputs you use. you aren't seeing the normal or the velocity before you assign it

stuck palm
#

recently learnt this lovely little operator

image.png
#

nice fallback if i ever forgot to set something in the inspector

languid spire
#

except it does not work with unity objects and should not be used with them

stuck palm
#

does it not?

#

how come

languid spire
#

would I say it didn't if I didn't mean it?

stuck palm
#

why doesnt it work

slender nymph
#

no, unity has overridden the == operator to handle destroyed objects when comparing to null. but the null operators like the null coalescing you are using do not use the overridden operator, so if an object is destroyed it will be == to null but not actually null

willow shoal
#

hi... how to make a block is visible after touching a block? "correctly and its working" some link or script? for this. im beginner

languid spire
#

because Unity handles null references differently than standard c# for it's objects

willow shoal
#

i need it notlikethis

stuck palm
#

i guess thats what this means then

slender nymph
#

yes

stuck palm
#

apparently you can't override the null coalesce operator

#

i wonder why

willow shoal
#

and what next?

slender nymph
# stuck palm apparently you can't override the null coalesce operator

correct, the null operators all do pure null checks. there's not typically a reason to override how null checks work, but since unity objects are created on the c++ side of the engine and can be "destroyed" there needs to be a way to represent that on the c# side which unity decided to make == null represent that

willow shoal
# 
  if (other.CompareTag("Player"))
    ```

Hey yo! I hope everyone is doing well this fine Monday. I was wondering if someone can point out my mistake? I am trying to clone Pong. I am trying to add sound and SFX. I have been able to get the backgorund music working and the sound when someone scores. What I am missing is getting the bounce sound to play when the ball bounces off of the players and the edge of the screen. I have tagged them all on layer 7. I have tried to copy the code that makes the score sound work. I am just not getting it to work. Would anyone be able to point me in the right direction?

let's say I have a rectangle with 4 triangles. I assign the second triangles as the first submesh and the third triangle as the second submesh.. what happens to the indexes?

seems to me they're getting jumbled?! is it [1, 2, 3, 4] -> [2,3,1,4]?! (always + the 2 following ofc)

teal viper
frozen plaza
#

a rectangle with 4 triangles

teal viper
#

Ah, so it's not the vertex indices.

frozen plaza
#

yes, it is

#

its 12 indexes for the 3 triangles but for brevity i cut it down / 3

teal viper
#

Then I don't understand what you're trying to say or ask.

frozen plaza
#

I want to know how the indexes of the triangles get reassigned in mesh.triangles when I assign the submesh

teal viper
#

Assuming you want a quad out of 4 triangles(with a vertex in the middle), you'd have something like 012 023 034 041 assuming 0 is the one in the middle. And I don't think submeshes are relevant to that at all🤔

queen adder
#

Hey im making a point system and the question is how can i move the ui component along the canvas?

image.png image.png
#

uning the set ofc

frozen plaza
#

hm.. I realize my question is wrong..

when I assign a material to that submesh.. what are the indexes for the vertices or triangles in that submesh (for the material or rather the shader)

teal viper
frozen plaza
#

and the triangles I pass in get reindexed from 0 then I guess?

teal viper
#

Should be, yes.

teal viper
frozen plaza
#

yea.. been testing out for a while now :>

#

but I always used .triangles

#

gonna try using .GetTriangles(submeshIndex)

ohh.. that ruins it a bit 😛

low wasp
#

Maybe you can tell me what I am doing wrong again or point me in the correct direction. If I add the if statement for a layer 7 collision it works when the game objects are checked at triggers. The problem this makes the ball pass right through and not bounce off. If I remove the is trigger check box. The ball bounces but the sound does not play. How do I get both to work? I have even tried to do a separated at the bottom but it does not work at all.

as long as you configure them properly

toxic frigate
# slender nymph be more specific than "isn't working"

in the code it is supposed to reject missiles tagged as "MissileTeamTwo" if the bool ScanForMissileTeamOne is set to true, and vice versa, however it still adds targets tagged as "MissileTeamTwo" if its scanning for missileteamone

slender nymph
#

well for starters you should be using the CompareTag method to check an object's tag rather than .tag ==. second, what debugging have you actually done?

tribal pelican
toxic frigate
#

i sprinkled debug logs in every if function in the IsTargetValid function, however they said that it was scanning correctly (if ScanForMissileTeamOne is true and the missile was tagged as MissileTeamOne it printed a log to the console) however it also said that it was ONLY seeing missiles tagged as MissileTeamTwo

tribal pelican
#

like, it doesnt recognize unity's syntax

slender nymph
tribal pelican
#

how do i do that

slender nymph
#

go through the guide and complete every step. you'll see the button if you actually do that

tribal pelican

i have done every step

there is no button

slender nymph

then you did not complete every step

oh

#

im just blind

#

nvm

slender nymph

restart visual studio after doing so

tribal pelican
#

okay, i did and theres no difference

#

it does spit out errors tho

if it is still not working then screenshot three things and show them here: 1. your external tools settings. 2. the vs editor package. 3. the entire visual studio window with the solution explorer visible

This is VS Code btw, make sure you selected the correct link

tribal pelican

#

vscode requires this to work properly with unity

tribal pelican
#

and how am i supposed to know that if its not written on the one page meant to explain how to use it

#

it says "Installing the Unity extension installs all its dependencies required to write C# with Visual Studio Code, including the C# Dev Kit." but apparently not

#

(this is also in the vscode output btw)

The command could not be loaded, possibly because:
  * You intended to execute a .NET application:
      The application 'restore' does not exist.
  * You intended to execute a .NET SDK command:

true

that goes over the entire process, including installation

you will be unlikely to have other issues because unlike vs code, visual studio doesn't require a lot of extra setup

just make sure you got the Unity Workload for VS Installer

oh okay

i'll try then

yea, the VSCode one is more raw and uses the dotnet command (usually can use this to make a new ,net app via command line)

can i disable the shitty autocomplete

do you mean intellicode? because if so, then yes. if you mean the regular intellisense, that is not recommended

I have this strange issue. I'm trying to bounce a projectile off of a wall, however, sometimes, it bounces off at weird angles/ignores the Normal?.As shown in the screenshot. The green trail is the projectiles actual movement, the minor red line is the raycast debug. The actual code for getting the reflect is the following, please ignore the weird Utils/other things, I was attempting a few different solutions

The weird thing is, it looks to be getting the inside of the mesh, and not the outside of it, causing it to reflect downwards instead of off the wall like I'd expect.

RaycastHit[] hits = Physics.RaycastAll(transform.position - transform.forward, transform.forward);
        foreach (var hit in hits) {
            Debug.Log("Hit: " + hit.collider.gameObject.name);
            if (Utils.WillLayersCollide(gameObject.layer, hit.transform.gameObject.layer)) {
                Vector3 hitNormal = hit.normal;
                Debug.Log(hitNormal);
                Vector3 bounceDirection = Vector3.Reflect(rb.velocity, hitNormal);
                rb.velocity = bounceDirection;
                Debug.Log("Bouncing");
                return;
            }
        }

slender nymph
#

RaycastAll does not guarantee an order for the returned hit objects. is there a specific reason you are using RaycastAll for this and not just a regular Raycast to get just the first hit?

# slender nymph yeah so you should probably switch to the singlular Raycast method and you can p...

Still happening with the following.

RaycastHit hit;
        if (Physics.Raycast(transform.position - transform.forward, transform.forward, out hit, 10f, Utils.GetCollisionMatrixLayerMask(gameObject.layer))) {
            Vector3 hitNormal = hit.normal;
            Debug.Log(hit.collider.gameObject.name);
            Vector3 bounceDirection = Vector3.Reflect(rb.velocity, hitNormal);
            rb.velocity = bounceDirection;
            Debug.Log("Bouncing");
            return;
        }

Where the util is

public static LayerMask GetCollisionMatrixLayerMask(int layer) {
        LayerMask collisionMask = new LayerMask();

        for (int i = 0; i < 32; i++) {
            if (!Physics.GetIgnoreLayerCollision(layer, i)) {
                collisionMask |= (1 << i);
            }
        }

        return collisionMask;
    }
#

And for reference the collider on the wall is just a good ol cube.

I need two physics GameObjects to detect each other's collisions but not interact / apply force to each other. I'm currently trying every combination of collider and rigidbody to no avail. The game is 2d.

Does anyone know what might be the cause of this mouse jumping?

I have a player empty gameobject with a movement script on it and a character controller, then I have a body inside of that which is just a capsule with a collider, then a camera in the body.

float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);

cameraTransform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);

you can do transform.position.x + 11f, x //this is the y float of a vector so i dont know why you have x here, 0 if you are looking for an offset. fixed it I got a little mixed up

Does anyone have an idea as to why the following code would give me a NullReferenceException for line 7?

When you use the ., you need to make sure the thing on the left side of it isn't a null reference.

#

All references start out as null and will be null unless you assign them somehow. Either in the inspector or with the = operator

#

Your reference here is private, so the inspector is not an option. Therefore you have to assign it somewhere with the = operator

If my object has a velocity, will its position be different between the Update and LateUpdate calls to a script?

wintry quarry
tepid frigate
#

Yeah the position/velocity of the rigidbody,

wintry quarry
#

Well it depends on a few things

#
  1. Do you have interpolation or extrapolation enabled on the body
#

I believe if you have interpolation on then yes the position may change between Update and LateUpdate

#

if you don't have interpolation on, then the Rigidbody position will only change during the physics simulation which is after FixedUpdate and before Update

tepid frigate
#

It seems I will want to use FixedUpdate instead of Update

wintry quarry
#

also note that Rigidbody.position and Transform.position can be different, especially with interpolation

wintry quarry
tepid frigate
#

Ok well my solution isn't working so well so here is what I am trying to do.
My characters are squares. Imagine square A and square B.
When A jumps on B, I want it so that when B moves, A also moves (like there is 100% friction).

I would use 100% friction except that would also mean when A moves, B also moves, which I dont want

#

I think the problem with FixedUpdate was that it didn't look smooth since it gets called less frequently than Update (sometimes)

wintry quarry
#

you want a platform

tepid frigate
#

wdym

wintry quarry
#

It sounds like you're taking about like having moving platforms for the character to jump on

tepid frigate
#

Like putting a platform on the characters head?

#

I will try that ig

wintry quarry
#

I'm asking a question

#

not making a suggestion

#

"a platform" doesn't really mean anything specific

bold plover
#

Any better than average state machine tutorials out there? Most of the ones I've been able to fine seem ghetto and have let me down.

tepid frigate
#

Its kind of like Pico Park mechanic, if you every played it

wintry quarry
tepid frigate
#

Like rn the characters can jump on each other, but since there is no friction, when the lower character moves, the upper character does not move with it

bold plover
#

Every day I learn there are a lot of tutorials out there that do more harm than good when you try to build on them. ;-;

Hey everyone, I am wondering if someone can give me some keywords to search for or straight up links to something that will help me acheive the following:

I want to create code that will help me simulate millions of games of a "connect-4-like" game to find out either; what the next best move is by weight, or just simply giving me statistics on who is more likely to win just by playing first.. etc.

any help is greatly appreciated... except a link to a connect-4 neuralnetwork github lmao. I'm trying to apply knowledge to my own game... connect-4 just closely resembles it. thanks!

Hey so I have this script for having an enemy turn to face the player via animations which turn it to face a specific angle. But when I want to to take its new angle into account when deciding how far to turn again it just wont work. When I have the current transform - rotation that faces the enemy it's a negative, and when I have the rotation towards the enemy - the current rotation than it gives me a completely different current rotation despite me not touching anything besides the transform.rotation.y - lookrot.y part.

image.png image.png image.png
wintry quarry
#

that's for chess not connect 4, but it should be applicable to any game.

wintry quarry
#

euler angles are not unique, as you are seeing

#

And there's no telling which of the many valid combinations of euler angles the Transform will give you back for any given rotation.

#

What are you trying to achieve exactly?

prime cobalt
#

I have this animation tree which turns a given amount of degrees. I'm trying to get the amount of degrees between the enemy's current rotation and the rotation which faces the enemy that need to be fed into this in order to turn.

image.png
#

I guess you could just contextualize it as getting the amount I would need to transform.Rotate between the current point and the one I need to face

wintry quarry
prime cobalt
#

Ok I'll try that out

tepid frigate
#

I want to be able to treat the characters as moving platforms.

Ok so I have it when character A jumps on character B, A.transform.parent becomes B.transform. Yet whenever B moves, A doesn't move. I have read it might be because I am using RigidBody2D with dynamic body type, but I have seen tutorials where it worked.

Is it because both A and B are dynamic, and B (the moving platform in this case), should be kinematic?

wintry quarry
#

Just playing with parenting and rigidbody body types won't get you the effect you need

I got a quesiton about lifecycle..

my GameObject instance is seemingly reinstantiated on a domain reload but neither Awake nor OnEnabled fire.. do I really have to catch OnAfterDomainReload statically and then roll that over on the instances by hand?

#

or should I just do all my initialization in the ctor?

wintry quarry
#

What is this causing an issue with

frozen plaza
#

I got some variables that come up null after the domain reload and I want to have it consistent.. I would want to reload the parts that need reloading but I'm thinking now.. if the object is completely reinstantiated I best just initialize everything fresh in the ctor

wintry quarry
#

what kind of variables?

#

Static variables or something?

prime cobalt
thorn fiber
#

I'm using a raycast to determine LoS between non-player entities. I'm a bit lost on finding anything but the target's center. Is there a way to work out the profile of a hit entity? (from there I could ray cast the left-most point, right-most, etc and get everything I need).

wintry quarry
#

maybe like 4-5 representative points for example

thorn fiber
wintry quarry
#

that's not going to be incredibly accurate depending on the shape of the object though

thorn fiber
#

the accuracy isn't a huge concern, as long it's not heading into jank territory. The main issue I want to overcome is where a unit may be partially viable behind something (say, terrain) but the ray cast will intersect the obstruction when looking at the center.

#

The more I think about it, the more I think the empty objects is the go. They detect each other via colliders, so instead of firing 1 ray cast at the entity (defaulting to center), I can loop the empty objects until I see one.

#

Thank you!

frozen plaza
# wintry quarry what kind of variables?

ok, so I got a couple member variables and I would set all this up in the ctor but MonoBehaviour can't have a ctor

UnityException: GetComponentFastPath is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'DO_Planet' on game object 'Planet'.
See "Script Serialization" page in the Unity Manual for further details.
UnityEngine.Component.GetComponentFastPath (System.Type type, System.IntPtr oneFurtherThanResultValue) (at <91ab5f1018a44edcbcbbe289ed4303bc>:0)
UnityEngine.Component.GetComponent[T] () (at <91ab5f1018a44edcbcbbe289ed4303bc>:0)
DO_Planet..ctor () (at Assets/_Scripts/Planet/DO_Planet.cs:62)

so what's the best way to initialize lifecycle wise.. needs to be availble after domain reload. Start, Awake, OnEnable are not called

wintry quarry
frozen plaza
wintry quarry
#

You can always just use a property

#

and lazy load it

# 
private Planet _planet;

public Planet Planet {
  get {
    if (_planet == null) _planet = GetComponent<Planet>();

    return _planet;
  }
}```
frozen plaza
#

I want to do initialization logic on this object though and I need the components

wintry quarry
#

do the initialization logic lazily too

#

It's all just... very vague to me

frozen plaza
#

meh :|

wintry quarry
#

you're saying you need initialization logic and all this stuff - and it's for an editor tool or something

#

seems like fields on a MonoBehavuour might be the wrong tool for it

#

It's not clear why your values are being reset if they're normal serialized fields

#

that's not supposed to happen

#

so something weird is going on here

frozen plaza
#

I just want to make sure the object is ready when I call things on it from my editor tool.. it's weird to me the object is being reinstantiated but there is no lifecycle hook and I can't use the constructor

wintry quarry
#

have you editor tool call an Initialize function

#

My guess is you're using nonserialized fields or something

#

which yes, will go away on a domain reload.

frozen plaza
#

marking the fields as [SerializeField] helped but now my issue is, I serialize a dictionary by hand:

[SerializeField]
  private Dictionary<int, DO_Planet_Biome> _biomeTriangles;
//---
    string json = JsonUtility.ToJson(_biomeTriangles, true);

the dictionary is definitely not empty but the json comes out {}

any idea why?

wintry quarry
frozen plaza
burnt vapor
#

JsonUtility can't serialize/deserialize common types

#

But even then, Unity can't show your dictionary in the inspector; you probably need to create a custom editor for it

wintry quarry
#

or grab a serializable dictionary off the shelf

stj is the best json serializer, so that's not true. can unity not include nuget packages?

wintry quarry
#

What makes it the "best" serializer in your opinion?
And no, Unity cannot use nuget packages out of the box

scenic maple
#

perf mostly

#

stj is a lot faster than anything else

wintry quarry
#

What are you basing that on?

scenic maple
#

like every source online. it's also fairly easy to benchmark yourself

#

but not really important if you can't use it anyway yep

wintry quarry
#

I can't find any source that compares Unity's JsonUtility with System Text Json

scenic maple
#

possibly because a comparison isn't easily possible

#

i would be very surprised if JsonUtility was anywhere near stj

wintry quarry
#

JsonUtility is pretty feature limited, and focused on speed

scenic maple
#

stj is made by the greatest minds at dotnet, it only makes sense that they know how to eek out every cpu cycle they can :p

wintry quarry

I wouldn't be surprised if it beats Newtonsoft

@wintry quarry So these are the two scripts:

Script 1: A Script designed to re-order bones of a SkinnedMeshRenderer to match another SkinnedMeshRenderer's bone order (using the root bone)

📎 script_1.txt
#

Script 2: A script that "Creates a new mesh based off the bone structure of a base mesh and ensures everything is in the correct order in the new mesh."

📎 script_2.txt
#

So my issue is that the second script works, but the results aren't as good as the first, as it does attach the new mesh to the bone order of whatever you are trying to mimmick, but does so with a lot of cavieats. One problem is that if the bone locations are even slightly off, the area where bones rotate around, will appear to be outside of the model, causing the rig to break. The first script is really good, looks the best, but does so by having a separate SkinnedMeshRenderer, and I want to end up with the ability to seamlesly switch the mesh in the SkinnedMeshRenderer without the bones breaking (if that makes any sense. Basically, combining the quality of the first script, with the end result of a seperate new mesh of the second.)

#

The second script does take into account the "bind pose" so I'm looking into that, but it's honestly so over my head all of this

Is there a way to make this (a unity scene file) show up in editor?

public Scene _scene;

I basically want to link a scene to a background music file. I could use the build index ofc, but just curious how to make the field show up in my inspector. 🙂

burnt vapor
#

Unless this changed in the past few years. it didn't when I used it

sand condor
#

Asked chatGPT and it says its not possible

burnt vapor
#

You can always make a custom editor

night raptor
#

They are not. It's Run-time data structure as the documentation tells

burnt vapor
sand condor
night raptor
#

You can find assets online for doing just that though

burnt vapor
#

I can't verify it (still) works. I suggest you try making your own from this reference

night raptor
#

It's shame the Scene assets are made so they cannot be easily referenced. I bet almost all larger Unity dev companies have made their own scene management tools to easily reference and manage their scenes

burnt vapor
#

I would not be surprised if there are readily available libraries that allow you to see Scenes and Dictionaries and all that in the inspector

#

Perhaps they haven't done it because it's opinionated, but it's not the only missing thing that you'd expect to just work

I posted about this yesterday with no real luck so I'm posting again this morning.

Im having this strange issue where when I'm trying to reflect projectiles off of a wall, they reflect off the inner portion of the collider, as seen in the photo. The green trail is the projectiles movement, the red debug raycast is the raycast seen below. I also checked the normal/hit position and debugged that, where it shows that it is inside of the collider at the normal you'd exepct to see in that photo. (Tho not the expected results.)

Any ideas?

RaycastHit hit;
        if (Physics.Raycast(transform.position - transform.forward, transform.forward, out hit, 10f, Utils.GetCollisionMatrixLayerMask(gameObject.layer))) {
            Vector3 hitNormal = hit.normal;
            Debug.Log(hit.collider.gameObject.name);
            Vector3 bounceDirection = Vector3.Reflect(rb.velocity, hitNormal);
            rb.velocity = bounceDirection;
            Debug.Log("Bouncing");
            return;
        }

Where the util is

public static LayerMask GetCollisionMatrixLayerMask(int layer) {
        LayerMask collisionMask = new LayerMask();

        for (int i = 0; i < 32; i++) {
            if (!Physics.GetIgnoreLayerCollision(layer, i)) {
                collisionMask |= (1 << i);
            }
        }

        return collisionMask;
    }

Sometimes you will need both namespaces, so you can specify which one to use by writing System.Random.Next() for example

Or use a using statement like a sane person

using UnityRandom = UnityEngine.Random;

...

code
{
  _ = UnityRandom.Next();
}

Everytime i tap on the screen a prefab "point" spawns for a few seconds to simulate touch on the mobile device, and then immediately destroys itself again.

Whenever another certain prefab is triggered by this point(by using collision), it is destroyed and i get added 1 point.

However i also want to make it so that when the background is accidently tapped, the console debugs: "FAILED" so i know it works and the player loses for missing the prefab.

This works, but whenever i tap the prefab, it both gives +1 point aswell as it debugs "FAILED" over and over again. As if it detects both the prefab and the background at the same time.
i tried changing the layer order but it still doesent work.

How can i make it in a 2D game, that a OnTriggerEnter2D of one object only applies to the next higher gameobject in a layer and not to those below it?

I have a question that I think I know the answer to. If I am creating games and I reuse my previous code for the new stuff. Is that wrong? I am thinking like player controllers, scoring systems, timers, and anything else that can get reused. My knee jerk answer is this is fine and kind of how it should be done. Don't reinvent the wheel every time. I can also see where this might be a crutch that holds you back from progressing in your skills. Thoughts?

slender nymph
#

there is no reason to reinvent the wheel every time you create a new project. reuse code when you can if it makes sense to
